gcc compiler error description

[Denis Tkachov]

Hi,

Would you tell me is there way to find description about g++ compiler
error code?

For example when I am building XCODE project from command line I am
getting such error:
ld: in TestCppDynamicLibrary.xcodeproj , can't map file, errno=22
collect2: ld returned 1 exit status

Where can I get description about error with number 22?

p.s. I am building xcode project from console because error provided
by xcode even less informative: "Command /Developer/usr/bin/gcc- 4.0
failed with exit code 1"

Best regards,
Denis
